A: Yes, but you’ll need two separate instances of acarsdeco2, each with a different serial number or device index ( --device-index 0 and --device-index 1 ).
Example NSSM command:
nssm install ACARSDeco2 "C:\acarsdeco2\acarsdeco2.exe" nssm set ACARSDeco2 AppParameters "--gain 40 --vdl2 --freq 136900000 --output C:\logs\acars.log" Then enable the service and reboot. Your verified decoder now runs silently, even without logging in. Decoding ACARS and VDL2 is legal in most jurisdictions because these signals are transmitted unencrypted in the VHF air band. However, you must never use the information (e.g., passenger names, flight crew messages, operational data) for malicious purposes, stalking, or redistribution that violates privacy laws. Verified decoders do not bypass encryption; they simply format what is already broadcast publicly. Frequently Asked Questions Q: Is acarsdeco2 better than dumpvdl2 on Windows? A: dumpvdl2 is Linux-native. ACARSDeco2 is the most reliable native Windows decoder. For most users, acarsdeco2 verified is the best choice unless you run WSL. acarsdeco2 windows verified
